Sediment load determines the shape of rivers [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance Rivers carry and deposit sediment, thereby shaping most landscapes around us. In doing so, their malleable channels change shape to accommodate the sediment load. Here, we show how fluid stress, gravity, and the erratic trajectories of traveling grains combine together to determine the shape of a river.

Estimating typical sediment concentration probability density functions for European rivers [PDF]
, 2005 Sediment in rivers is linked with qualitative and quantitative water problems throughout Europe. Sediment supply and transfer are part of a natural process of minimising gradients in the landscape.

The impact of intermittency on bed load sediment transport [PDF]
Geophysical Research Letters, 2021 AbstractSediment transport by wind or water near the threshold of grain motion is dominated by rare transport events. This intermittency makes it difficult to calibrate sediment transport laws, or to define an unambiguous threshold for grain entrainment, both of which are crucial for predicting sediment transport rates. We present a model that captures

Impact of coarse sediment supply from hillslopes to the channel in runoff-dominated, dryland fluvial systems [PDF]
, 2014 Sediment supply from hillslopes to channels is an important control on basin functioning and evolution. However, current theoretical frameworks do not adequately consider processes of runoff-driven hillslope sediment supply, which affect river channels ...

Lateral sediment sources and knickzones as controls on spatio-temporal variations of sediment transport in an Alpine river [PDF]
, 2013 Modern mixed alluvial-bedrock channels in mountainous areas provide natural laboratories for understanding the time scales at which coarse-grained material has been entrained and transported from their sources to the adjacent sedimentary sink, where ...

Measurement of spatial and temporal fine sediment dynamics in a small river [PDF]
, 2012 Empirical measurements on fine sediment dynamics and fine sediment infiltration and accumulation have been conducted worldwide, but it is difficult to compare the results because the applied methods differ widely.
